Antibacterial phages combined with magnetic nanoparticle clusters effectively kill infectious bacteria found in water treatment systems. A weak magnetic field draws the clusters into biofilms that protect the bacteria and break them up so the phages can reach them.

NASA continues to study pulsars, 50 years after their chance discovery
These rotating 'lighthouse' neutron stars begin their lives as stars between about seven and 20 times the mass of our sun. Some are found to spin hundreds of times per second, faster than the blades of a household blender, and they possess enormously strong magnetic fields.
New imaging tracer allows early assessment of abdominal aortic aneurysm risk
Researchers have developed a way in which medical imaging with SPECT/CT could potentially be used to assess a patient's rupture risk for abdominal aortic aneurysm. Delaying surgical treatment can be life-threatening, and this new type of imaging could allow physicians to diagnose disease and better plan its management.
Technique enables printable and rewritable color images
A chemical process that allows color images to be printed on specially coated paper and then erased so that different images can be printed on the same paper has been developed.
Magic helps unmask how the brain works
Scientists have used the 'mirror box' illusion -- an old magic trick - in a number of neuroscience studies. Researchers are using a new version of the illusion to study how the brain processes multiple sensory inputs to perceive our bodies and the world around us.
No simple way of predicting breathing difficulties in pugs, French bulldogs and bulldogs from external features
As many as a half of all short-nosed dogs such as pugs, French bulldogs and bulldogs experience breathing difficulties related to their facial structure. However, research suggests that there is no way to accurately predict from visible features whether an apparently healthy pug or French bulldog will go on to develop breathing difficulties.
Dietary restriction can improve learning in worms
Dietary restriction -- the reduction of a specific nutrient or total dietary intake without triggering malnutrition -- increases longevity and improves learning, but are these processes regulated separately? A new study indicates that the answer is 'yes.'
Chemical weathering could alleviate some climate change effects
Scientists have discovered that chemical weathering, a process in which carbon dioxide breaks down rocks and then gets trapped in sediment, can happen at a much faster rate than scientists previously assumed and could potentially counteract some of the current and future climate change caused by humans.
Noise helps cells make decisions
Random differences between cells early in development could be the key to making different cells in the body, according to new research. Different cell types -- brain, blood, skin, gut etc. -- all have unique and vital roles, yet they all start out the same. Cells become different as a result of a long sequence of biochemical choices made before we're born. For us to be healthy, these choices need to ensure we get the right number of each cell type.
Effects of cognitive behavior therapy on parents of children with autism
Researchers have discovered that parents who participate in cognitive therapy with their children with autism also experience improvements in their own depression, emotion regulation.
Size matters, and so do temperature and habitat, to scavengers and the carcasses they eat
Size matters in the carrion world, and so do habitat and temperature. New research has shed fresh light on the largely understudied area of vertebrate scavenging ecology.
For white middle class, moderate drinking is linked to cognitive health in old age
Older adults who consume alcohol moderately on a regular basis are more likely to live to the age of 85 without dementia or other cognitive impairments than non-drinkers, according to a new study.
Smart underwear proven to prevent back stress with just a tap
Unlike other back-saving devices, this one is mechanized and was tested with motion capture, force plates and electromyography.
New algorithm finds the optimal bond breaking point for single molecules
Recent developments in atomic-force microscopy have enabled researchers to apply mechanical forces to individual molecules to induce chemical reactions. A research team has now developed a first-of-its-kind algorithm that determines the minimal force it takes to reach the optimal bond breaking point (BBP) at the molecular level to mechanically induce a chemical reaction.
Steroid treatment for type of kidney disease associated with increased risk for serious infections
Among patients with IgA nephropathy and excess protein in their urine, treatment with pills of the steroid methylprednisolone was associated with an unexpectedly large increase in the risk of serious adverse events, primarily infections, according to a study. IgA nephropathy is a kidney disease that occurs when the antibody immunoglobulin A (IgA) lodges in the kidneys.
